"Are you alright? ”

By the time Eric came to his senses, Catelyn's piercing eyes were reading his expression.

"It's fine, just a little tired. Eric knew that the reason was terrible, and Caitlyn must have guessed something.

"This is not your time to be hypocritical, detective, and don't forget, Leonardo is still missing. Chiko almost grabbed Eric's ears.

"Hmm-" Eric hesitated slightly, but Caitlin was staring at him with an indescribable look, making him feel as if there was a camera inside him that was monitoring all his mental activity, "I think I probably know." ”

"What?" Chiko was shocked and thought that she had misheard, the rogue detective who had been confused before suddenly became enlightened in an instant?

"Don't play any tricks!" Chiko warned, uneasy.

Eric didn't answer, he stood up, looked solemn, took a deep breath, and walked forward a few meters. Chiko saw Eric close his eyes and grope his hands left and right on a few pieces of masonry. She was about to speak when Caitlyn stopped her and made a gesture to silence. Caitlyn's eyes are telling Chiko to believe in Eric.

After a while, Eric's right hand suddenly stopped. He opened his eyes and nodded at Caitlyn. Caitlin was stunned for a moment, as if she understood something. She walked back to the loose masonry from earlier, and pressed down two pieces of masonry with Eric. But when the two pieces of masonry were pressed down 3 centimeters, nothing unusual happened.

"And then. Chiko had a puzzled expression.

"Listen. Caitlin seemed to notice something.

Chiko immediately held her breath, and sure enough, there was an intermittent whimper under her feet. The whimper is soft, but the echo is able to reach the ground. The three of Eric followed the sound, and finally saw Leonardo with a cloth ball in his mouth and his hands tied behind his back under the manhole cover in the corner.

"But that's not the case under the manhole just now. Chiko asked incredulously.

"Let's go down first. Caitlin pulled open the manhole cover and jumped first.

Leonardo, who was rescued, looked at the three people indignantly: "You guys came too late, damn it, there was a mouse stepping on my head just now!"

"Where is this?" Chiko ignored Leonardo's complaints, and when she looked up, the manhole cover they had jumped into was gone, replaced by an old stone slab with the alchemical marks found on the ground.

"Didn't this groggy detective tell you?" Leonardo glared at Eric, "This is the passage to Bacchus' tomb. ”

Eric was silent, speechless.

"I also know something about the Catacombs of Bacchus, the entrance to which should not be in the Place de Danfer-Rochereau, in the fourteenth arrondissement of Bacchus"

"Don't be naïve, if you go in from there, do you know how many passes you have to pass to get rid of the eyes of the police?" Leonardo interrupted Caitlin's doubts, "Bacchus's underground tunnels are very complicated, but it also attracts a lot of young people who like urban adventures to explore here, so gradually a lot of routes and entrances have been developed, I bet that the underground tunnel map in the hands of those people is definitely more complete than that of Bacchus City Council." ”

"You mean this place can lead to the PX-0 target without even noticing?" Chiko was a little incredulous.

"Of course, this is the most mysterious route of the Bacchus underground tunnels. Leonardo put his hands on the tunnel wall, his eyes fixed on the root of the wall, carefully searching for something, "I went from here to my destination two years ago with this bastard detective. But times have changed, and I need to look for a marker. ”

Eric saw Chiko glaring at him, apparently believing that he had deceived her. But Eric was also very distressed, could he be sleepwalking now, or the same person he was two years ago......

"This is it!" Leonar crouched down, picking up the twigs at his feet to scrape the dust from the ground, and turned back to Eric with a smug look. Chiko and Caitlyn gathered around to see that it was still the symbol of alchemy.

Eric showed a mocking expression, pointing to the symbol and mocking Leonardo: "It's ridiculous, I thought you were only obsessed with whiskey and strippers, but I didn't expect you to be obsessed with alchemy, a neurological scientist who believes in turning stones into gold?

Leonardo heard Eric's sarcasm and was about to go up to fight. But Caitlyn immediately made a gesture of stopping, and she gently patted Leonardo on the shoulder, as if to soothe a red-eyed pit bull.

Leonardo, who was very useful, rolled his eyes at Eric, and then pointed to the straight line of the symbol and explained: "Just go in the direction of this straight line, find the next symbol, and find three symbols in a row to find the entrance to the underground tunnel." ”

The three of them immediately searched in the direction of the straight line, and finally found an entrance to the sewers. Caitlyn and Chiko open the manhole cover of the sewer, and the four of them climb down the improvised iron ladder. Eric took one last look at the alchemist's symbol, and he remembered that Hugo's Notre-Dame church also had an alchemist-obsessed vicar, and that this Notre-Dame church was exactly the place he remembered to meet Leonardo, could it be just a coincidence?

"Eric!" At this time, Chiko was already urging from below. Eric shook his head and quickly climbed down.

"Oh~ here, it's crazy!" As soon as he stepped down the last staircase, Eric saw the "uniqueness" of the sewer: graffiti and signatures painted in various colors on the walls and floors, and some streamers and beer bottles floating in the ditches of the sewers. Apparently it was once a place for urban adventurers to celebrate and revelry.

Eric looked at the walls and floors carefully, but still had no memory of the place in his mind. He pointed to the colorful wall and asked Leonardo, "Do you think I can't remember anything of this kind of bizarre place?"

Leonardo, looking for any of his former "masterpieces" on the walls, replied obliviously: "Who knows, maybe you're playing with some bad idea?"

"Look!" Catelyn found the alchemical symbol on the ground around a corner, "Does this symbol mean to enter from here?"

Leonardo nodded, and the four turned on their flashlights and followed the markers. Moments later, the four found a hole. After crawling 10 meters from the hole, Eric and his party set foot on this land full of death.
